I'am using a Telecom Italian Mobile SIM.
I can't connect with it,  this is my code:
while(notConnected)
 {
   if[font=Verdana](gsmAccess.begin(PINNUMBER)==GSM_READY)[/font]
     notConnected = false;
   else
   {
     Serial.println("Not connected");
     delay(1000);
   }
 }

It don't work with gsmAccess.begin(PINNUMBER), the SIM has disable the PIN, if i don't write a value to PINNUMBER the script stop at gsmAccess.begin(PINNUMBER) instruction, if i write a "0000" value, the real SIM PIN value, it answer "Not connect".
Any suggestion ?

-------------------------------------------------------
#include <GSM.h>

// PIN Number
#define PINNUMBER "0000"

// initialize the library instance
GSM gsmAccess;     // include a 'true' parameter to enable debugging
GSMScanner scannerNetworks;
GSMModem modemTest;

// Save data variables
String IMEI = "";

// serial monitor result messages
String errortext = "ERROR";

void setup()
{
 // initialize serial communications and wait for port to open:
 Serial.begin(9600);
 while (!Serial) {
   ; // wait for serial port to connect. Needed for Leonardo only
 }

 Serial.println("GSM networks scanner");
 scannerNetworks.begin();
 
 // connection state
 boolean notConnected = true;
 
 // Start GSM shield
 // If your SIM has PIN, pass it as a parameter of begin() in quotes
 while(notConnected)
 {
   if(gsmAccess.begin(PINNUMBER)==GSM_READY)
     notConnected = false;
   else
   {
     Serial.println("Not connected");
     delay(1000);
   }
 }

I solved.
My SIM is not authorized to connect GPRS!!!

I understood this using the GSM gsmAccess (true) instruction to have a debug on the serial port:
AT+CGREG?%13%
9 40>AT+CGREG?%13%%13%%10%[font=Verdana]+CGREG: 0,3[/font]%13%%10%%13%%10%OK%13%%10%

+CGREG: 0,3 means: 'not registered, access denied'
